Hint: Use trial and error procedure to identify the critical crack length required for brittle fracture Integrate Paris law numerically to obtain number of cycles to failure Problem 3 (40 marks) The cross-section of a prototype gun barrel is shown in the figure below. Under repeatod firing, the barrel rapidly develops an array of 40 radial cracks, which undergo fatigue growth as a result of cyclic pressurization. It is a requirement that the fatigue life of the barrel, based on...
